The Why system is an indoor pendant luminaire that creates endless arrangement possibilities in office spaces. The luminaire can shine in four directions – downwards, upwards and sideways. An efficient light source with dynamically changing light colors is installed in its side walls, which makes it possible to illuminate particular space segments of floors with different colors. The luminaire can be equipped with an opal diffuser or a louvre. This ensures a very low glare coefficient, which significantly increases working comfort.
